Abalone is one of the common food materials, and it belongs to a kind of expensive food materials. According to the category to which abalone belongs, they are fish in the genus Abalone of the family Abalone of the primitive gastropoda of Gastropoda of Mollusca. It can be seen that abalone belongs to mollusks and shellfish. Some people think that abalone belongs to a kind of fish because of the word "fish" in its name. In fact, this view is a misunderstanding. Abalone is not a fish, and it is quite different from fish, so it cannot be confused with them. Abalones are soft inside, and have a hard calcareous shell on the outside to protect their bodies.

From the living environment, abalone lives in seawater, so it can be said to be a marine animal. From the specific distribution of abalone sea areas, they are widely distributed in the sea areas around the world, including the Pacific Ocean, Atlantic Ocean and Indian Ocean. In the northeast of China, abalone is also a traditional production area. From the perspective of eating habits, abalone's favorite food is algae, among which Undaria pinnatifida, goose intestines and horsetail are all very popular among abalone. Whether wild abalone or cultured abalone, their main food is plants.

As mentioned above, from the living environment of abalone, they inhabit the ocean, that is, salt water with high salinity. Abalones live in salt water for a long time, and their bodies have already adapted to the environment with high salinity, so they generally cannot live in fresh water and adapt to the environment with fresh water. From the specific distribution sea area, abalone is still very extensive, because they are distributed in the other three oceans except the Arctic Ocean.
